Too many loops detected, check your while condition error

Can't figure out what done wrong. Appreciate help.

Boolean answerIsNo; do { String response = console.readLine("Do you understand do while loops?: "); if (response.equals("No")); { answerIsNo = true;} } while (answerIsNo);

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.

Boolean answerIsNo;
do {
  String response = console.readLine("Do you understand do while loops?:  ");
  if (response.equals("No")); {
    answerIsNo = true;}
} while (answerIsNo);

Hey there Isiah was close on this, just the small error of declaring response with a String in front of it, thought you were trying to declare the same variable twice. Try the code below.

String response;


do {

// For the first task:  (Delete 'String' on the second task),
response = console.readLine("Do you understand do while loops?");



} while (response.equalsIgnoreCase("No"))

console.printf("Because you said %s, you passed the test!", response);

Thanks, feel free to shout if there's any trouble with this.

Try this:

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;

// The second,
do {

// For the first task:  (Delete 'String' on the second task),
String response = console.readLine("Do you understand do while loops?");


  // The second,
} while (response.equals("No"));

// And the third:
console.printf("Because you said %s, you passed the test!", response);

Tried your example but I'm getting error: variable response is already defined in method run() String response = console.readLine("Do you understand do while loops?: "); In the exercise it requires response to be declared as a string variable outside the do loop. Thoughts?

Super close! Note your unneeded semicolon:

if (response.equals("No")); {

Every time through the loop you were setting it because that line ends right there. It probably will work better ;)
